Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84578, here are decompositions:

  • 19 + 84559 = 84578
  • 79 + 84499 = 84578
  • 97 + 84481 = 84578
  • 157 + 84421 = 84578
  • 229 + 84349 = 84578
  • 271 + 84307 = 84578
  • 331 + 84247 = 84578
  • 349 + 84229 = 84578

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 84578 first appears in π at position 123,749 of the decimal expansion (the 123,749ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
